Evaluating the effects of near-field earthquakes on the behavior of moment resisting frames
Following the 1994 Northridge and 1995 Kobe earthquakes, most of modern structures damaged seriously or devastated totally despite the seismic codes of these countries that had been expected to bear advanced criteria for seismic design of structures. After extensive research, the most probable reason of those destructions was attributed to special specifications of near-field earthquakes. In th...
متن کاملLarge Earthquakes and Crustal Deformation Near Taiwan
Source parameters of 15 large (mb -> 6) earthquakes which occurred near Taiwan during the last 25 years are determined by synthetic seismogram analysis of teleseismic P and S waveforms. Source depths range from 13 to 88 km. Three earthquakes of intermediate depth are located within the southernmost limit of the Ryukyu arc and show thrust-type mechanisms with T axes subparallel to a northward di...
متن کاملevaluation of coupled- shear walls subjected to near-field earthquakes
coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...
متن کاملEffects of Far- and Near-Field Multiple Earthquakes on the RC SDOF Fragility Curves Using Different First Shock Scaling Methods
Typically, to study the effects of consecutive earthquakes, it is necessary to consider definite intensity levels of the first shock. Methods commonly used to define intensity involve scaling the first shock to a specified maximum interstorey drift. In this study the structure’s predefined elastic spectral acceleration caused by the first shock is also considered for scaling. This study aims to...
متن کاملA Strong Ground Motion Catalogue of Selected Records for Shallow Crustal, Near Field Earthquakes in Iran
Understanding strong ground motions in the near-fault areas is important for seismic risk assessment in densely populated areas. In the past, lack of information on strong ground motion for large and moderate earthquakes led to the use of mainly far field large and moderate earthquake records in equations for calculation of the strong ground motion parameters. In this article, we collected and ...
